其中，上述第一 DCI格式对应的 PDCCH信息基于预编码的方式进行传输，上述第二 DCI格式对应的 PDCCH信息基于非预编码的单天线端口方式或发送分集方式进行传输。 The PDCCH information corresponding to the first DCI format is transmitted according to a precoding manner, and the PDCCH information corresponding to the second DCI format is transmitted according to a non-precoded single antenna port mode or a transmit diversity mode.

其中，上述第一 DCI格式对应的 PDCCH信息可以承载在上述子帧的数据信道区域中，即承载在 D-PDCCH , 如图 9所示。 The PDCCH information corresponding to the first DCI format may be carried in the data channel region of the subframe, that is, carried in the D-PDCCH, as shown in FIG. 9.

其中，上述第二 DCI格式对应的 PDCCH信息，优选地，可以承载在上述子帧的控制信道区域中，如图 10所示，或者可选地，还可以承载在上述子帧的数据信道区域中，如图 11所示。可选地，若第二 DCI格式对应的 PDCCH信息调度的数据信道在第二载波上时，则第二 DCI格式对应的 PDCCH信息承载在第一载波上的控制信道区域中。其中，第一载波为后向兼容的载波，其上有 CRS传输；第二载波为非后向兼容的载波，如扩展载波 ( extension carrier ) 或载波片段 ( carrier segment ) , 其上没有 CRS传输。 Preferably, the PDCCH information corresponding to the second DCI format may be carried in the control channel region of the subframe, as shown in FIG. 10, or alternatively, may also be carried in the data channel region of the subframe. , as shown in Figure 11. Optionally, if the data channel scheduled by the PDCCH information corresponding to the second DCI format is on the second carrier, the PDCCH information corresponding to the second DCI format is carried in the control channel region on the first carrier. The first carrier is a backward compatible carrier with CRS transmission thereon; the second carrier is a non-backward compatible carrier, such as an extension carrier or a carrier segment, and no CRS transmission thereon.

具体地，当子帧为多播广播单频网（ Multicast Broadcast Single Frequency Network, 简称 MBSFN )子帧时，如果第二 DCI格式对应的 PDCCH信息承载在上述 MBSFN子帧的控制信道区域中，则上述 UE在上述 MBSFN子帧中，可以基于专用参考信号（Dedicated Reference Signal, 简称 DRS )检测上述第一 DCI格式对应的 PDCCH信息，以及基于小区参考信号（ Cell Reference Signal, 简称 CRS )检测上述第二 DCI格式对应的 PDCCH信息； Specifically, when the subframe is a Multicast Broadcast Single Frequency Network (MBSFN) subframe, if the PDCCH information corresponding to the second DCI format is carried in the control channel region of the MBSFN subframe, the foregoing The UE may detect the PDCCH information corresponding to the first DCI format, and detect the second DCI based on a Cell Reference Signal (CRS) based on a dedicated reference signal (DRS) in the MBSFN subframe. The PDCCH information corresponding to the format;

如果第二 DCI格式对应的 PDCCH信息承载在上述 MBSFN子帧的数据信道区域中，则上述 UE在上述 MBSFN子帧中，可以基于 DRS检测上述第一 DCI格式对应的 PDCCH信息，以及基于 DRS或截短的 CRS检测上述第二 DCI格式对应的 PDCCH信息。 If the PDCCH information corresponding to the second DCI format is carried in the data channel region of the MBSFN subframe, the UE may detect the PDCCH information corresponding to the first DCI format and the DRS based on the DRS in the MBSFN subframe. The short CRS detects the PDCCH information corresponding to the second DCI format.

具体地，当子帧为非 MBSFN子帧时，上述 UE在上述非 MBSFN子帧中，可以基于 DRS检测上述第一 DCI格式对应的 PDCCH信息，以及基于 DRS或 CRS检测上述第二 DCI格式对应的 PDCCH信息。 Specifically, when the subframe is a non-MBSFN subframe, the UE may detect the PDCCH information corresponding to the first DCI format based on the DRS in the non-MBSFN subframe, and detect the second DCI format corresponding to the second DCI format based on the DRS or the CRS. PDCCH information.

所谓基于 DRS检测 PDCCH信息，具体是用 DRS来做信道估计，进而对 PDCCH信息进行检测（例如：解调、解码等）。其中， DRS为基站发送给 UE的， DRS在子帧中的位置是预先定义的。 The so-called DRS detection of PDCCH information is specifically performed by using DRS for channel estimation, and then detecting PDCCH information (for example, demodulation, decoding, etc.). The DRS is sent to the UE by the base station, and the location of the DRS in the subframe is predefined.

所谓基于 CRS检测 PDCCH信息，具体是用 CRS来做信道估计，进而对 PDCCH信息进行检测（例如：解调、解码等）。其中， CRS为基站发送给 UE的， CRS在子帧中的位置是预先定义的。 The detection of PDCCH information based on CRS is specifically performed by using CRS for channel estimation, and then detecting PDCCH information (for example, demodulation, decoding, etc.). The CRS is sent to the UE by the base station, and the location of the CRS in the subframe is predefined.

所谓基于截短的 CRS检测 PDCCH信息，具体是指， MBSFN子帧的数据信道区域本没有 CRS,为了检测 PDCCH信息，基站可以只在这个 UE 的 PDCCH信息所在的时频资源上发送 CRS, 即截短的 CRS, 用该截短的 CRS来做信道估计，进而对 PDCCH信息进行检测 (例如：解调、解码等 )。 The detection of PDCCH information based on the truncated CRS specifically refers to the MBSFN subframe. The data channel area does not have a CRS. In order to detect the PDCCH information, the base station may send the CRS, that is, the truncated CRS, only on the time-frequency resource where the PDCCH information of the UE is located, and use the truncated CRS to perform channel estimation, and then perform PDCCH on the PDCCH. Information is detected (eg, demodulated, decoded, etc.).

可选地，上述第一 DCI格式可以为与上述传输模式对应的 DCI格式，例如： DCI格式 1、 2、 2A、 2C或 4等；相应地，上述第二 DCI格式则为多个传输模式共有的 DCI格式，例如： DCI格式 0或 1 A。 Optionally, the foregoing first DCI format may be a DCI format corresponding to the foregoing transmission mode, for example: DCI format 1, 2, 2A, 2C, or 4, etc.; correspondingly, the foregoing second DCI format is shared by multiple transmission modes. The DCI format, for example: DCI format 0 or 1 A.

可选地，上述第一 DCI格式还可以为多个传输模式共有的 DCI格式，例如： DCI格式 0或 1A; 相应地，上述第二 DCI格式则为与上述传输模式对应的 DCI格式，例如： DCI格式 1、 2、 2A、 2C或 4等。 Optionally, the foregoing first DCI format may also be a DCI format shared by multiple transmission modes, for example: DCI format 0 or 1A; correspondingly, the foregoing second DCI format is a DCI format corresponding to the foregoing transmission mode, for example: DCI format 1, 2, 2A, 2C or 4, etc.

需要说明的是：在 103之前， UE还可以进一步通过上述基站发送的 RRC专有信令，获知需要检测上述第一 DCI格式和上述第二 DCI格式对应的 PDCCH信息，即让该 UE进入 D-PDCCH的检测模式。 It should be noted that: before the 103, the UE may further detect, by using the RRC dedicated signaling sent by the base station, that the PDCCH information corresponding to the first DCI format and the second DCI format needs to be detected, that is, the UE enters the D- Detect mode of PDCCH.

本实施例中，通过 UE根据基站配置的传输模式，确定传输模式对应的第一 DCI格式和第二 DCI格式，使得 UE能够在子帧中检测上述第一 DCI 格式和上述第二 DCI格式对应的 PDCCH信息，从而实现了 PDCCH信息在 D-PDCCH上检测。 In this embodiment, the first DCI format and the second DCI format corresponding to the transmission mode are determined by the UE according to the transmission mode configured by the base station, so that the UE can detect the first DCI format and the second DCI format corresponding to the second DCI format in the subframe. The PDCCH information, so that the PDCCH information is detected on the D-PDCCH.

本实施例中，如果信道状态难以准确反馈，例如： UE高速移动场景下，那么基站则无法获取准确的信道状态，从而无法在子帧中，基于该信道状态的预编码的方式发送第一 DCI格式对应的 PDCCH信息。此时，基站则可以在子帧中，基于非预编码的单天线端口方式或发送分集方式发送第二 DCI格式对应的 PDCCH信息，通过 UE在子帧中检测上述第一 DCI格式和上述第二 DCI格式对应的 PDCCH信息，使得 UE能够准确检测出第二 DCI格式对应的 PDCCH信息，从而进一步提高了 PDCCH信息的检测可靠性。 In this embodiment, if the channel state is difficult to accurately feed back, for example, in a high-speed mobile UE scenario, the base station cannot obtain an accurate channel state, and thus cannot transmit the first DCI in a subframe based on the precoding of the channel state. The PDCCH information corresponding to the format. In this case, the base station may send the PDCCH information corresponding to the second DCI format in the non-precoded single antenna port mode or the transmit diversity mode in the subframe, and the UE detects the first DCI format and the second in the subframe. The PDCCH information corresponding to the DCI format enables the UE to accurately detect the PDCCH information corresponding to the second DCI format, thereby further improving the detection reliability of the PDCCH information.

本实施例中，如果基站通过 RRC专有信令，通知 UE需要检测上述第一 DCI格式和上述第二 DCI格式对应的 PDCCH信息，但是基站尚未接收到 UE反馈的该 RRC信令正确接收的确认信息之前，基站则无法确认 UE 是否正确接收到上述 RRC专有信令。此时，基站则可以在子帧中，基于非预编码的单天线端口方式或发送分集方式发送第二 DCI 格式对应的 PDCCH信息，通过 UE在子帧中检测上述第一 DCI格式和上述第二 DCI 格式对应的 PDCCH信息，使得 UE能够准确检测出第二 DCI格式对应的 PDCCH信息，从而进一步提高了 PDCCH信息的检测可靠性，实现了两种 PDCCH检测模式间的平滑过渡。 In this embodiment, if the base station passes the RRC dedicated signaling, the UE is notified that the PDCCH information corresponding to the first DCI format and the second DCI format needs to be detected, but the base station has not received yet. Before the RRC signaling fed back by the UE is correctly received, the base station cannot confirm whether the UE correctly receives the RRC dedicated signaling. In this case, the base station may send the PDCCH information corresponding to the second DCI format in the non-precoding single antenna port mode or the transmit diversity mode in the subframe, and the UE detects the first DCI format and the second in the subframe. The PDCCH information corresponding to the DCI format enables the UE to accurately detect the PDCCH information corresponding to the second DCI format, thereby further improving the detection reliability of the PDCCH information, and implementing a smooth transition between the two PDCCH detection modes.

其中，数据信道的传输模式的详细描述可以参见图 1 对应的实施例中的相关内容。 For a detailed description of the transmission mode of the data channel, refer to related content in the corresponding embodiment of FIG. 1.

202、上述基站确定上述传输模式对应的 DCI格式，上述 DCI格式为第一 DCI格式或第二 DCI格式； 202. The foregoing base station determines a DCI format corresponding to the foregoing transmission mode, where the DCI format is a first DCI format or a second DCI format.

203、上述基站在子帧中，根据上述 PDCCH信息传输的方式向 UE发送上述 DCI格式对应的 PDCCH信息。 203. The base station sends, in the subframe, PDCCH information corresponding to the DCI format to the UE according to the manner of transmitting the PDCCH information.

其中，上述第二 DCI格式对应的 PDCCH信息，优选地，可以承载在上述子帧的控制信道区域中，如图 10所示，或者可选地，还可以承载在上述子帧的数据信道区域中，如图 11所示。 The PDCCH information corresponding to the second DCI format, preferably, may be carried in The control channel region of the foregoing subframe, as shown in FIG. 10, or alternatively, may also be carried in the data channel region of the subframe, as shown in FIG.

可选地，若第二 DCI格式对应的 PDCCH信息调度的数据信道在第二载波上时，则第二 DCI格式对应的 PDCCH信息承载在第一载波上的控制信道区域中。其中，第一载波为后向兼容的载波，其上有 CRS传输；第二载波为非后向兼容的载波，如扩展载波 ( extension carrier ) 或载波片段 ( carrier segment ) , 其上没有 CRS传输。 Optionally, if the data channel scheduled by the PDCCH information corresponding to the second DCI format is on the second carrier, the PDCCH information corresponding to the second DCI format is carried in the control channel region on the first carrier. The first carrier is a backward compatible carrier with CRS transmission thereon; the second carrier is a non-backward compatible carrier, such as an extension carrier or a carrier segment, and no CRS transmission thereon.

需要说明的是：在 203之前，基站还可以进一步通过向 UE发送 RRC 专有信令，指示 UE检测上述 DCI格式对应的 PDCCH信息，即让该 UE 进入 D-PDCCH的检测模式。 It should be noted that, before 203, the base station may further send the RRC dedicated signaling to the UE, and instruct the UE to detect the PDCCH information corresponding to the DCI format, that is, let the UE enter the detection mode of the D-PDCCH.

In this case, the base station may send the PDCCH information corresponding to the second DCI format in the non-precoding single antenna port mode or the transmit diversity mode in the subframe, thereby further improving the transmission reliability of the PDCCH information. In this embodiment, the base station notifies the UE that the PDCCH information corresponding to the first DCI format and the second DCI format needs to be detected by using the RRC dedicated signaling, but the base station has not received the acknowledgement that the RRC signaling is correctly received by the UE. Before the information, the base station cannot confirm whether the UE correctly receives the above RRC proprietary signaling. In this case, the base station may send the PDCCH information corresponding to the second DCI format in the non-precoded single antenna port mode or the transmit diversity mode in the subframe, thereby further improving the transmission reliability of the PDCCH information, and implementing two PDCCHs. A smooth transition between detection modes.
